Usually cars come with the wheels buried inside the quarter panels or front fenders. To bring them out a little and have a flush fitment look you can purchase and install wheel spacers. This vehicle has 15mm wheel spacers in the rear and 10mm wheel spacers in the front. As you can see the fitment is perfect.

Did you install extended lugs or did the 10mm and 15mm fit without any problems?

If you get 10mm or larger spacers, you will absolutely need to get extended bolts. I tried a 10mm spacer with the OEM bolts just to see how it would look (didn't drive on them). The OEM bolts barely had about 2 revolutions of bite.

If you decide to use the OEM bolts, be sure to video tape it and upload it to YouTube. You'll become famous like this dude.
